Three additional deaths (from metastatic lung cancer, left ventricular failure, and hepatic neoplasm) occurred during the 6-month post-treatment safety monitoring period, all in patients receiving the standard of care. No significant correlation was found between the incidence of splenectomy and any other baseline variable.

Splenectomy is not considered an appropriate first-line therapy for most patients with immune thrombocytopenia,2 and many nonsurgical treatments either are poorly tolerated or fail to produce durable responses. The purpose of this study was to determine the safety profile and maximum tolerated dose (MTD) of romiplostim and to investigate whether romiplostim accelerates platelet recovery post-UCBT. Romiplostim should not be used in an attempt to normalize platelet counts. Please refer to this study by its ClinicalTrials.gov identifier (NCT number): NCT01444417. Blood. Since no single drug has been established as the standard treatment for immune thrombocytopenia, we compared romiplostim with a variety of standard-of-care therapies.

The lower incidence of serious adverse events in the romiplostim group (occurring in 23% of patients) as compared with the standard-of-care group (37% of patients) indicates that romiplostim is a generally safe treatment option for patients, relative to other therapies for immune thrombocytopenia.

The higher rate of a platelet response and lower incidence of treatment failure in the romiplostim group were also associated with a marked reduction in the need for splenectomy, which was performed in 9% of patients in the romiplostim group and 36% of patients in the standard-of-care group.

Immune thrombocytopenia is an autoimmune disease characterized by low platelet counts due to both increased platelet destruction and suboptimal platelet production.1 After initial treatment with glucocorticoids or intravenous immune globulin or anti-D immune globulin, most adult patients require second-line medical therapy (e.g., azathioprine or rituximab) or surgical therapy (i.e., splenectomy).2 However, most first- and second-line medical treatments are short-acting, have severe side effects, or are potentially toxic.2-4 These problems can adversely affect the health and quality of life of patients.

Kao YR, Chen J, Narayanagari SR, Todorova TI, Aivalioti MM, Ferreira M, et al. Romiplostim or Standard of Care in Patients with Immune Seketes states that romiplostim should not be used routinely in MDS based on this clinical trial; however, it appears reasonable to consider use in patients with bleeding due to low platelet counts who do not respond to transfusions and in whom aminocaproic acid has been unsuccessful. Dose Adjustments Use the actual body weight at initiation of therapy, then adjust the weekly dose of Nplateby increments of 1 mcg/kg until the patient achieves a platelet count 50x109/Las necessary to reduce the risk for bleeding; do not exceed a maximum weekly dose of . Lancman and colleagues (2018) stated that thrombocytopenia is a relatively common complication following allogeneic HSCT and is associated with increased bleeding, transfusion requirements, chronic GVHD, and all-cause mortality. The time to treatment failure was significantly longer in the romiplostim group than in the standard-of-care group (P=0.02) (Figure 2A). Thrombocytopenia was most common, occurring in 3% of patients (5 of 154) receiving romiplostim and in 12% of patients (9 of 75) receiving the standard of care. Do not use romiplostim in an attempt to normalize platelet counts. Safety end points included bleeding events, blood-product transfusions, and laboratory results. nplate mechanism of action radiation. George JN, Kojouri K, Perdue JJ, Vesely SK.
